If you haven't checked out maps.google.com yet, you should. Not only does the map capability totaly rule compared to everyone else (realtime dragging around of the map - no refresh needed), but they just added satellite capabilities courtesy of their child company Keyhole. You can zoom down to within a few city blocks of your address (in popultaed areas). If you think this is cool, I've seen the standalone Keyhole software zoom in even closer, down to a few meters. It is seriously cool...
